# Blocking rulesets Verifone's Blocking Rulesets feature enables merchants to set certain rules, based on which transactions are automatically blocked by Verifone, without informing the cardholder of the transaction decline reason. As a result, merchants can save fees for transactions that are not forwarded for further processing. If the transaction activates a blocking ruleset, it is declined by Verifone. {% embed url="" %} {% embed url="" %} ## Availability The Blocking Rulesets in Verifone Central can be applied only to eCommerce transactions. They can be created by users with a **Merchant Admin** role and need to be applied at **Merchant Organization** level or they can be used for all Child Organizations. \ **Merchant Reviewer, Merchant** **Supervisor**, **Merchant User** roles can only view (read) the Blocking Rulesets.
